Which does not answer my question. Does OWC pay an import duty for the SSD drive?
What happens on the production side has zero impact on the retail side. There's really no other way to say it at this point. Your question is useless for whether the
final retail transaction has a duty, which is the issue for international pricing.
If yes, it does not really matter if I pay the duty or OWC (because OWC will hand it over to me via their final price).
Of course they pass on added costs; the issue here you're apparently not getting is
when there are added costs.
If you're in the US and buy from OWC,
there is no added duty. If you're in some other country and buy from them, there
are usually added import costs. The cost for OWC to buy from its suppliers is the same in either case, so asking whether OWC paid a duty is immaterial. The transaction that has
different costs is
selling the product to you, based on whether you're a domestic or international customer.
That added international cost can be expressed in the price from the seller (as Apple does with its international sales) or billed separately for the customer to pay (as many small businesses do).
That assumes that I care about import costs. I care about total costs Apple has to ship one iPad to a customer. And this total cost is probably dominated by costs on the production side.
You
do care about import costs, because you made the bizarre claim that there wouldn't be a difference between buying domestically in the US compared to overseas markets. That's what this whole discussion has been about.
If the iPad costs $300 to produce, all in, and it's $200 for overhead and profit, then it sells for $500 shelf price in the US.
To sell in country X, where there's $45 in import duties from the US and costs and $5 in international business costs, the price grows to $550. Production costs are still the same $300, and base overhead is still $200. If they then have a 10% VAT, the shelf price will be $605--thus explaining why the X shelf price is 21% higher than the US shelf price.
